What We Offer:
Weight Loss Medication
Prescription weight loss medication is commonly used to make you feel less hungry or fuller.
Weight Loss Surgery
Surgery involves making surgical changes to your digestive system to help you lose weight
Weight Loss Medications
Prescription weight loss medication is commonly used to make you feel full or less hungry. Most medication is administered by injection on a weekly basis. Candidates are those with a BMI of 27 or above.
Injectable Weight Loss Medications
Many prescription weight loss drugs are glucagon-like peptide-1 (GLP-1) agonists. These injectable medications mimic the GLP-1 hormone, which your body releases after eating to let your brain know you’re full. They slow the movement of food through the stomach to help you feel full longer. GLP-1 medications are also effective for treating Type 2 diabetes. They signal the pancreas to produce more insulin to prevent blood sugar spikes after eating.
We offer several weight loss medications through My CHS Rx, including:
- Mounjaro® (tirzepatide)
- Ozempic® (semaglutide)
- Wegovy® (semaglutide)
Bariatric Surgery
Bariatric surgery involves making surgical changes to your digestive system to help you lose weight. There are several different surgery options and the type of weight loss surgery that is best for you depends on your health and individual situation. Candidates are those with a BMI of 35 or above with one comorbid condition present such as diabetes, high blood pressure, high cholesterol or sleep apnea.
How it helps with Weight Loss:
Bariatric surgery changes how your digestive system works. It reduces the size of your stomach to help you feel full faster and eat less. In some procedures, it lowers levels of the hunger hormone (ghrelin) and may reduce the calories your body absorbs from food.
Body mass index (BMI) is a calculation that estimates your body fat percentage based on your height and weight. It helps your provider know whether your weight is a health issue you need to address.
Frequently Asked Questions
Obesity doesn’t have a single, direct cause. Obesity can be a chronic condition or develop over time due to certain behaviors or underlying conditions. Factors that may contribute to weight gain include:
- Certain medications
- Genetics
- Lack of physical activity
- Lack of sleep
- Mental health conditions including depression and anxiety
- Poor eating habits
- Stress
- Underlying health issues like metabolic syndrome
We offer weight loss treatment for individuals with a BMI of 30 or higher — or 27 and higher if accompanied by a weight-related health condition. These conditions include Type 2 diabetes, high blood pressure, sleep apnea and more. A specialist conducts a full examination and consultation with a patient to determine if they qualify and will then decide on the best method of treatment based on individual needs.
You will work directly with one of our weight loss specialists to determine the program that will work best for you based on your health, lifestyle and weight loss goals. They will review each option with you to develop a personalized care plan that fits your needs and sets you up for lasting success.
We recommend checking with your insurance provider to find out the details of your plan’s coverage. You may be able to use a flexible spending account (FSA) to save on medical weight loss costs.
